I think this would make a really nice present for your inner child!

The “ultimate boy toy” as it was called in its press release, is the work of a British engineering lecturer, that managed to transform it from a regular H3 model, to a remote-controlled one. And it only took him one month’s time to do it. Impressive feat if you consider that it can climb a 16-inch vertical wall and maneuver in up to two feet of water.
